The graph shows the range of frequencies commonly heard by some animals. A graph with frequency in Hertz on the axis from 0 to 100, 000. On the y axis are porpoise, bat, moth, cat, human, bird, fish, cricket and snake. Porpoise is 60 to 105,000 Hertz. Bat is 55 to 100,000 Hertz. Moth is 250 to 100,000 Hertz. Cat is 60 to 80, 000 Hertz. Human is 20 to 12,000 Hertz. Bird is 65 to 9000 Hertz. Fish is 80 to 2000 Hertz. Cricket is 55 to 1,000 Hertz. Lastly snake is 100 to 1000 Hertz. Which animals can hear a sound wave that has 18,500 cycles in 0.75 seconds? Check all that apply.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
